I'm using R12 Jdeveloper and after every couple of minutes it becomes very slow and i have to close it and open it again in order to work properly. Is there any thing i can do to fix this issue? This is really frustrating. Any help is greatly appreciated.
1. Terminate the OC4J when you are in design mode.
2. Delete the contents from the file XXXX--oc4j-app.log (under myprojects folder).
3. Go to tools->preferences->code editor->code insight and set the value to something smaller
I had faced similar issue sometime back and above trick did work for me to some extent.
